IMPROVEMENT IN GRAIN-BINDERS.

Specication forming part of Letters Patent No. 88,087, dated March 23, 1869.

To'all `whom it may concern :V

lBe it known that 1, G. B. SHAFER, of Delta,

in the county of Fulton and lState of Ohio,

have invented a new and useful Improvement inGrain-Binding Machines; and I do hereby declare that the following isa full, clear, and` exactdescription thereof, which will enable arel delivered to it,.and discharge them when so bound, all as will be more fully described hereinafter, on reference to the accompanying drawings, wherein- Figure l represents a plan view of my improved machine. Fig. 2 represents a trans-y verse sectional elevation on the line x x, Fig. 1, and Figs. 3 to 9 represent detail views.

Similar letters 'of reference `indicate like parts.

The attachment is designed to be secured to the framing of a reaping-machine in such amanner that the receiver A will be adapted to receive the bnndlesof grain as they are delivered by the rakes from the apron of the machine. The arrangement which I prefer is to so attach A,it that the .end A1 will be presented in the direction in which the machine moves, and directly behind the drivingwheels, so that the receiver will take the grain from the near or left side of the said apron, and whereby a, platform or seat may be provided for the attendant, who directs/the operations ofthe machine by means of the hand-cranks A2 A3, and forces the bundles to the bottom ofthe receiver, and compresses them as much as possible previous to the windin g ofthe binding-cord around them by the hand-crank A4, to which the compressingarm A5 is attached. The binding-cord B is supplied from a spool, Bl, arranged .in suitable brackets, and carried through the axis of the shaft B3, and over suitable guide-pulleys to the winding-head B3, supported on a bent arm projecting from the inner end of the sh aft B2. 'C represents another winding-head, provided with a roller,-1C,.hav

ingpins projecting from its periphery, `which is so geared `with reference to the windinghead B3 and otherwise .arranged as to be caused tomove into the path of the said head B3 and in `contact therewith as it .is moved around the bundlelying in the receiver A.. The face of the carrying-head B3 isgprovided with a 4ridge or lprojection b, through which lthe cord projects, also with vgroove b1 and l2 and a curvedguide, b3.

When the said winding-heads approach each other they meet in Ithe `direction represented by the arrow b, thevpi'n G1 standing inthe direction indicated at C2, enteringpthegroove b of the head B3, wh-ile the end G3 ofthe head C enters the curved .groove of the same, and the curved projection b` enters the space C4, between the wheel Gland the end'03 ofthe head G.` As the two heads .thus engaged continue in their respective courses past each other, theend ofthe cord`B,pro jectin g through one of the holes shownin the projection-b, will bedrawn into the space G4, and the wheel C1 will be turned around by the action of the wall of the inclined groove b', so as toloop the cord around or past a pin, Ci?, `Fig..6, and v cause it` to assume the position represented at-CG, Fig. 7, which will hold the cord with snfcient lpower to enable the head C to retain tvand carry it around the loopers, as will presently appear, while the other winding-head B3is delivering the cord aroundthebuudle. `As the wall of the ygroove b1 will not vturn the wheel G1 fully into the desired positioutbr holding the cord, as representedin Fig. 7, auother groove, b2, and a curved .guide,.b4, are provided in the head B3under `such an arrangement as to receive the next piu of the `wheel C succeeding .the onebeing acted on by the wall ot' the groove bl, and in a similar mannereifect the full movement of the said wheel G1.

These winding or carrying heads `are operated from the driving-shai'tD, which is com mon to both, the one B3 through the wheels D1, D2, and D3, and carries the yarn around the bundle after having delivered the end to vthe head G,as above described; andthe other,

C, through the wheels D4, D5, and D5, and

winds the yarn around the loopers E, and it is so arranged that it is capable of sliding parallel with its axis of motion, and is provided with a leven-E1, taking into a groove in its hub, for giving the said4 sliding motion, the said lever being vibrated' by a grooved camwheel, E2, on the shaft of the wheel D5. The groove in the saidlcam-wheel is so formed that it will cause the sliding head C to recede sufficiently after having taken hold of the yarn to allow it to wind the yarn on the loopersth rough one revolution, and at the beginning` ofthe second revolution to pass up to the head B3, coming into contact .with it,taking hold of the yarn a second time and winding the yarn for a part of the said revolution on the projecting en d of the shaft E3, which is provided with a pin, E4, for the purpose of hooking the yarn so wound on it and drawing it within the loop formed on thel loopers E, and which is discharged therefrom over the part drawn in by the recession of the rod E3, which simultaneously turns the points of the loopers E down against the said shaft to discharge the said loop.

The recession of the said shaft is effected by a spring, E5, when the lever which, by the action of the cam E7, moves the shaft in the opposite 'direction has arrived at the notch in the cam which permits the said spring to act. Before the winding-head C has completed its second revolution and is so thrown forward as to come into contact with the head B3 and take another hold of the cord, the latter is then severed at the head B3 by the knife e, the operation of which will be presently described. The said head C now holds both ends of the cord, which it winds onto the shaft E3 just previous to its recession, which effects the tying of the knot, as before described.

The said ends are disconnected from the carrying-head C by a knife, F, on the saidv head, which is actuated at the proper moment by the shank F1 thereof coming into contact with the fixed arm F3.

The cutter e, which severs the yarn from the head B3, is supported on a sliding shank, el, which is set into motion at the proper time, immediately after having delivered the' yarn to the head C, the second time by the curved bell-crank e?, pivoted to the frame below the wheel D3, which is provided with a lug, e4, whichcomes in contact with one end of the bell-cranke2 and moves it in the direction to operate the knife e. After its operation the said knife is retracted by a spring, e3.

' The driving-Wheels D1 and D4 are fixed loosely upon the drivin g'shaft D, and provided with clutches connected by suitable bell-cranks to the stop-levers G1, arranged to spring into notches in the disks (J2, to stop the movements of the winding-heads at the proper point. The said stop-levers arealso connected by suitable links lto the hand-cranks A2 and A3, byl

which the operator raises them out of connection with the notches in the said disks, and at the same time slides the cluthes G into gear with the wheels Dl and D4, setting them into motion, the driving-shaftD being always in motion.

To effect the discharge of the bundle after it is thus bound from the receiver, the latter is made in two parts, the lowermost A4 being hinged at A5, and provided with a balanceweight, A5, which will restore it to the closed position after discharging a bundle. It is also provided with a sliding catch, which takes under a projection of the strengtheningrib H1, as represented in dotted lines in Fig. 1, and holds it up underthe weight of the bundle until the movement of the recession of the lever E5, which'strikes an elbow H2 of the said slide and withdraws it from under the said lug, allowing the' said swinging part ofthe receiver to fall at the moment that the knot is tied in the yarn, when the loperator kmay cause the necessary movement of the follower I in the receiver by the handcrank Il to eject the bundle, the said hand-crank being arranged in connection with said follower by means of a chain or spring, l2, and alpiston, l5.
